FAT

Krill oil / marine phospholipids

Fat — also: NKO, krill, krill oil

One ingredient, seen the whole way through: what it is, how it works, the honest evidence, the form that matters, the systems it touches, and the studies behind it.

EmergingCell

200mg krill fraction in MarineOmega, paired with undisclosed-dose astaxanthin. A small positive RCT exists for krill oil in PMS symptoms (Sampalis 2003), but the 'krill crosses the blood-brain barrier better' claim is marketing framing, not RCT-backed. Structure/function only.

How it works

  • Build — delivers EPA/DHA bound to phospholipids rather than triglycerides, a form that incorporates directly into cell membrane structure

  • Exchange — phospholipid form is studied for supporting membrane fluidity and fatty-acid transport

  • Maintain — krill oil naturally contains astaxanthin, the same carotenoid antioxidant that helps protect its own omega-3 fatty acids from oxidation in the capsule and, proposed but less proven, within the body after absorption

  • Exchange — the phospholipid-bound EPA/DHA form is digested via a different pathway than triglyceride-bound fish oil -- phospholipase rather than pancreatic lipase -- the basis (though not yet conclusively proven head-to-head) for claims that krill-bound omega-3s may be absorbed somewhat more efficiently at matched doses

Form matters

The same nutrient can be made in very different forms — and a study done on one form does not automatically apply to another. Methylcobalamin is not cyanocobalamin; magnesium glycinate is not magnesium oxide; a whole-food extract is not the synthetic isolate that was studied. Two things decide whether what is in the bottle behaves like the research: the exact form, and independent lab verification (a Certificate of Analysis) that the form and dose on the label are truly what is inside. Without a COA, you are trusting a label, not the science.
